<p>Hi !</p>
<p>We have different carriers, some of them send contact in ACK & BYE, some not, but problem persist only when in-Dialog<br>
messages have Record-Route header. I can't put here real conversations, but can reproduce signaling in lab.</p>
<p>Here is the signaling & debug log without contact in ACK, with Record-Route header present.<br>
